Abstract: 247,799. Wujanz, G. May 18, 1925. Gear-cutting. - A toolhead for a machine for generating straight or skew bevel gears by planing, comprises a member 2 rotated for the generating movement about the axis 5 by worm gearing 3 and carrying a tool-holding plate 11 pivoted about the axis of an eccentric shaft 7 which is driven from an oscillating wheel 9 and which transmits reciprocating motion to the racks 14, 14<1> of the tool slides 15, 15<1>, through pinions 12, 13, 12<1>. In a modification, the pinion 10 may be actuated by a rack reciprocated from a crank. The guides 18, 18<1> carrying the tool slides are adjustable about the pivot pin 17 carrying the pinion 12<1> and the cutting-edges of the tools 22, 22<1> are always directed towards the axis of the pin 17. The angle between the guides 18, 18<1> is indicated by a scale 21. For planing straight teeth the axis of the pin 17 coincides with the axis 5, Fig. 5, but for planing skew teeth the plate 11 is first swung about the axis of the shaft 7 according to the obliquity of the teeth required and the tool guides are then adjusted about the pivot 17 so that the medium line of the crown wheel tooth reciprocated by the tools passes through a fixed point 20, and the angle between the lines of cut of the tools is the required angle a. It is shown that the fixed point 20 lies on the line joining the axes 5 and 7, and the axis 5 and the point 20 are equidistant from the axis 7. When the cutting tools are adjusted in this way, the lines of cut are tangential to a common circle as shown in Fig. 1. A second scale 24 is provided to facilitate adjustment of the plate 11.
